Because sodium hydroxide is a strong base and carbonic acid is a weak acid.
NiCl2 + Na2CO3 = NiCO3 + 2NaCl
Sodium carbonate is dissociated in water.
Red litmus paper turn blue in basic solutions; sodium carbonate solution is basic.
The chemical reaction isȘCaCl2 + Na2CO3 = CaCO3 + 2 NaCl
Because sodium hydroxide is a strong base and carbonic acid is a weak acid.
When dissolved in water, Na2CO3 dissociates into two ions. The carbonate can pull hydrogen ions away from water molecules, leaving hydroxide ions. The hydroxide ions are what causes the solution to be basic.
Na2CO3 +H2O----->HCO3++OH-HERE HCO3- IS A WEAK ACID AND OH- IS A STRONG BASE
Na2CO3 +H2O----->HCO3++OH-HERE HCO3- IS A WEAK ACID AND OH- IS A STRONG BASE
Na^+ (aq) and CO3^2- (aq)
